Transparent Protein Microtubule Motors with Controllable Velocity and Biodegradability
Slender
protein microtube motors with a catalase interior surface
are self-propelled in aqueous H<sub>2</sub>O<sub>2</sub> by jetting
O<sub>2</sub> microbubbles from the open-end terminus. Immobilization
of a catalase biocatalyst on the internal wall is achieved using avidin–biotin
complexation. It is particularly interesting that the migration of
O<sub>2</sub> bubbles in the 1D channel and their subsequent expulsions
were clearly visible because the tube walls are transparent. The microtube
motor velocity reached a maximum at the optimum pH and temperature
of the catalase. Furthermore, the microtubes were digested completely
by proteases, showing sufficient biodegradability
